To all whom it may concern:

Be it known that I, Join: L. ALLINeroN, a citizen of the United States, residing at Joplin, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Rock or Dirt Drags, of which the following is a specification.

This invention relates to rock or dirt drags, and it comprises a curved body portion having ribs or teeth secured thereto and projecting below the lower edge, a (shaped yoke having its arms secured to the back of the body portion and having the free ends of the arms arranged at an angle, whereby they are substantially horizontal when the body portion is in operative position, means for securing a rope or cable to the free ends of the arms, and means for attaching a rope or cable to the back of the body portion.

In the present invention, I have produced a drag particularly useful in moving piles of gravel, sand, or other granular material Then material of this sort is being shoveled from a pile to a car, the laborers begin to work on the side of the pile nearest the car track. As a portion of the pile is shoveled away, it becomes necessary for the workmen to carry shovelfuls of material several steps from the edge of the pile to the car in which it is being loaded. By the use of the present invention, the material forming the pile may be dragged to a point adjacent the car and thus loaded without performing unnecessary manual labor.

The invention is also capable of being used in various other ways,wherein loose granular material is to be moved or con veyed from one place to another.

In the present invention, I have provided a simple device having means for maintaining the drag in operative position when power is applied to move it forward. I have further provided means wherein the drag may be dumped and returned to the source of material in inoperative position.

In the accompanying drawings, I have shown one embodiment of the invention. In this showing:

ranged adjacent each edge be. adjusted transversely on Patented Nov. 22, 1921. Serial No. 423,297.

Fig. 3 is a rear elevation of the drag, and,

Fig. 4 is a side elevation thereof.

Referring to the drawings, the reference numeral 1 designates the body portion of the drag which, as shown, comprises a substantially rectangular plate of suitable rigid materlal such as metal or the like. As shown,

the body portion is curved to enable the drag to retain material therein. On the rear side of the drag, reinforcing plates 2 are arand near the bottom. A plurality of ribs or teeth 3 are secured to the front of the drag, and as shown, these teeth project slightly beyond the lower edge.

A. Y-shaped yoke l is secured to the drag in'any suitable manner, the forward ends of the arms of the Y being arranged on the back of the body portion, as at 5, and secured thereto by means of bolts 6 and nuts 7. The arms are bent, as at 6, and extended at an angle to the lower portion 5, whereby the remainder of the yoke will be in a substantially horizontal position when the body portion of the drag is in operative position (see Fig. {2). The ends of the arms are substantially parallel to each other, as at 7, and a U-shaped clip 8 is secured thereto, the clip'being provided with an eye 9, for the reception of a loop 10, arranged on the end of a rope or cable 11. As shown, the end of the cable is passed through the eye and secured by suitable fastening means 12.

A pair of eyes 13 are arranged on the back of the body portion of the drag near the upper edge. Connecting rods or links 14 are arranged in these eyes and are provided with eyes 15 on their free ends for the reception of a ring 16. The cable 17, having a loop 18, is adapted to be received in this ring, the end of the cable being passed through the ring and secured by suitable fastening means 19. This cable extends rearwardly and passes over a pulley 20 carried by a supporting member 21. The supporting member is supported on a transverse cable 22, arranged at a suitable elevation whereby the lower end thereof engages the ground or other surface to retain the member in substantially vertical position. The supporting member ma the cable 22, being loosely mounted thereon by means of an eye 23, through which the cable passes.

arranged In operation, the device is properly assembled at the point where it is to be used by arranging the cable 22 behind thematerial to be moved, and at right angles to the intended direction of travel of the drag. The supporting member 21 is then placed in position and cable 17 is passed over-the pulleyQO. The two cables 11 and 1"? are then mounted on suitable pulleys or drums (not shown), whereby power is supplied, the drums or pulleys being adapted to revolve in opposite directions. The drag is then brought into operativeposition over the pile of materialltobe moved, and the teeth 3 dig into the material whereby thedrag is filled. Power is then applied to wind on the pulley or drum and unwind the'cable 17, the drag being moved forward in the position shownin Figs. 1 and 4 of thedrawings. The curvature of the body-portion of the drag and the angle of the Y-shaped yoke is such that force being applied at theend of the yoke willinove the drag forwardin the position shown in Figs. 1 and i of the has been moved drawings, and moved in front drag is wardly and the reinforcing plates 2 form the traction with the ground wherebywear on the body portion is minimized. At the end ofthe return travel when the power is again reversed, the force applied to the cable 11 will return'the drag to normal operative position and additional force applied will move it forwardly in operative position.

It is to'be understood that the form of my invention herewith shown and described is to be taken as a preferred example of. the same, and that various changes, in the shape, size, and arrangement ofparts maybe resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

' 1. In a device of the character described a drag, comprising a curved body portion, a yoke secured thereto,

a cable to the free end of the yoke, said. end

the cable 11 7 upper edge thereof,

means for securing being arranged at an angle, whereby power applied will maintain the body portion in a substantially vertical position, securing means arranged on the back of the body portion and so disposed that t ie drag will. assume a power is applied thereto.

2. In a device of the character described a drag, comprising afourved" body portion, teeth arranged on the front thereof, a yoke secured to the body portion, means for securinga cable to the free end of said yoke, said free end being arranged and. cable horizontal position wheir of the body por- 1310B and oro ectino' below the lower ed e l J o c at an angle whereby powerapplied thereto will maintain the body portion in a substantially vertical'position, and cable securing means arranged on the back of the-body portion and so disposed; that the drag will assume a horizontal positionwhen power is applied thereto. 1

3. A rock drag, comprising a curved body portion, a plurality of teeth secured to the front of the body portion and projecting beyond the lower edge thereof, reinforcing plates secured to the back of the body portion, near each side, a yoke secured to the body portion, means for securing a cable to the free end of said yoke, said free end being arranged at an angle whereby power applied thereto will maintain thebody portion in a substantially vertical position, and cable securing means arranged body portion and so disposed that the drag will assume a horizontal position and rest on said reinforcing plates when power is applied thereto. l

4:. A rock drag, comprising. a curved body portion, a yoke secured thereto, means for said free end being arranged at an angle on the back of the whereby power applied thereto will main-{ tain the; body portion in a substantially vertical position, a pair of eye-bolts secured to the back of the body portion near the rods connected to said eye-bolts, a ring secured to the other'ends of said rods and adapted to receive acable whereby the drag may be moved rearwardly in a horizontal position.

In testimony whereof I affix my signature in presenceof two witnesses.
